Sadly, I assumed this would be the outcome. I believe the perp knew the family and knew that Hania liked to go start the car in the morning, so he was there for that opportune time when he would have her and a car. I do not believe this is a random act by a random person. She, or her family, was targeted <modsnip - off topic>.
I believe she was grabbed, killed, dumped and the perp is no longer anywhere near the area. I believe he was sent to kill one of the children and he, too, is a Guatemalan and likely here illegally.
I am sorry that the dad can't attend his child's funeral, but that is one of the consequences of living in a different country than your family - you may not be able to get there if there is a funeral, birth, marriage, illness, etc. Did they come here with him and he returned or did they come alone? Why is he not with, and supporting, his family?
It is sad, but it is a decision they made for themselves and now, the consequences are heartbreaking.
